Procedure

A solution of 4.0 g of the product from Example 15 and 2.2 g of 4,6-dimethoxy-2-aminopyrimidine in 29 ml dry acetonitrile was heated to ca. 60° C. for 11/2 hours and then stirred at room temperature overnight. The product, which had precipitated, was collected and washed with 1-chlorobutane and then dried in vacuo. The yield of N-[(4,6-dimethoxypyrimidin-2-yl)aminocarbonyl]-1-(2-nitrophenyl)ethanesulfonamide was 3.1 g white solid, m.p. 168°-170° C.
